From Linus Walleij, Ux500 defconfig patches for the v3.13 rc series:
- Allow creation and mounting of devtmpfs, which is used
by OpenEmbedded root filesystems among others.
- Enable CPUidle for the ux500, it has been accidentally
disabled due to a Kconfig change.

Revert "ARM: ux500: Stop passing MMC's platform data for Device Tree boots"
Revert "ARM: ux500: Remove AUXDATA relating to SDI (MMC) clock-name bindings"
This reverts commit 49c129519a.
The special settings for the SD/MMC card parameters that are not
yet fully agreed upon how to encode into the device tree went missing
with this commit. We need to first put it into the device tree,
and then remove the platform data.

Also, clean-ups to remove duplicate defines and document a hardware

ntb: Fix missed call to pci_enable_msix()
NTB: Fix NTB-RP Link Up
NTB: Xeon Doorbell errata workaround
The emulated bridge does not support interrupts, so it should return the
value 0 for Interrupt Line and Interrupt Pin. This indicates that
interrupts are not supported.
Since Max_Lat and Min_Gnt are also in the same 32-bit word, we return
0 for them, which means "do not care."
This corrects an error message from the kernel:
pci 0000:00:01.0: of_irq_parse_pci() failed with rc=135
Which is due to the default return of 0xFFFFFFFF indicating that
interrupts are supported.
The error message regression was caused by 16b84e5a50 ("of/irq: Create
of_irq_parse_and_map_pci() to consolidate arch code.")

The above mentioned commit didn't go far enough. Well, it covered the
function tracer by adding checks in __register_ftrace_function(). The
problem is that the function graph tracer circumvents that (for a slight
efficiency gain when function graph trace is running with a function
tracer. The gain was not worth this).
The problem came with ftrace_startup() which should always be called after
__register_ftrace_function(), if you want this bug to be completely fixed.
Anyway, this solution moves __register_ftrace_function() inside of
ftrace_startup() and removes the need to call them both.

The flexcan IP core uses the peripheral clock ("per") as basic clock for the
bit timing calculation. However the driver uses the the wrong clock ("ipg").
This leads to wrong bit rates if the rates on both clock are different.
This patch fixes the problem by using the correct clock for the bit rate
calculation.
